<p>The present invention relates to a connecting structure for water service pipes, which reduces the weights of fittings, simplifies the structure of a connection part, and easily connects the water service pipes. To this end, the connecting structure for water service pipes of the present invention reduces the weights of the water service pipes and the fittings for connecting the water service pipes by using steel pipes and has a socket unit, which is increased in diameter and integrated with a fixing flange having fastening holes, at an end of the pipe. A compressing band is fastened to an end of another connecting pipe or a fitting fitted into the socket unit so that the connecting pipes can be simply connected to a primary water service pipe. A separation preventing ring, which keeps watertightness by pressurizing packing when the compressing band and the socket unit are fastened and prevents separation by pressurizing the connecting pipe, is prevented from being inserted into the socket unit so that the connecting pipe is tightened enough not to be separated.</p> |
